The membrane biofouling of IAFMBR was conducted using
transmembrane pressure (TMP) (Fig. 4). Granular active carbon
(GAC) addition and temperature control was used for studying
membrane fouling. According to the pervious researches, 40 g
GAC was a proper dosage here (Gao et al., 2014), which was dosed
into the inner tube (AnMBR) at each temperature. In order to
examine the one-time operational duration of membrane biofouling,
no backflushing or clean-up was employed.
